“…For example, "my friends think it's fine to go out drinking more than once a week" (Rimal & Real, 2003). Individuals appear to generally overestimate the quantity and frequency of their peers' drinking behaviour (Borsari & Carey, 2001;Carcioppolo & Jensen, 2012;Halim, Hasking, & Allen, 2012), as well as peer approval of drinking and risk-taking (Iwamoto, Cheng, Lee, Takamatsu, & Gordon, 2011;Kenney, LaBrie, & Lac, 2013), which in turn influences behaviour 6 . Individual observations about their peers' behaviour once intoxicated, and perceived peer approval of alcohol-induced risk-taking, would therefore seem a worthy consideration in the alcohol and risk-taking literature.…”
